Really intrigued with this! I too tried the "new" version, but ultimately had to go back to the more stable 2.5. Now my issue is that I have trouble getting my universe going, so I may blatantly steal from this!
You may be going into more detail, but I am curious about how your tournaments are working. Do you have a specific amount of time between fights based on the scheduled rounds? So if you have a 12 round bout, how soon before the 15 rounder?
